A lens bracket 189 extends from the plate 180 and supports the lens barrel 190 with the lenses 191 and 192. Posts 193 extend up from the cover E and have respectively journaled' thereon the guide rollers 194 and 195.

In Figs. 13, 14 and 15 is shown a modifitable and guide cone.

' The armature shaft 61 in this 'modification has provided therefor a journal hanger 200 extending from the cover E; Adjacent to the ban er 200 there is fastened to the armature sha 61 a worm 201. The spindle 82 is shown supported at its lower end in the journal bearing 46 with its thrust ball 83. A ball bearing race 202 has the lower threaded portion 203 for the nut 204. A- washer 205 is inte between the cover E and the nut 204. The said race 202 is clamped to the cover E by means of said nut. The turntable designated by the numeral 206 has extending therefrom the sleeve207 having the notches 208. Apin 209 extends through the spindle 82 and engages the notches 208. A ballbearing cage 210 with the ball bearings 211 is sup-' ported upon the' race 202 and encircles the sleeve 207. The guide cone 212 is journaled on the spindle 82 and bears u n the turntable 206. On the spindle 82 is astened a worm wheel 215 which meshes with and is driven by the worm 201. The worm wheel From the late driving mechanism'of the turn{ 215 drives the spindle 82 and thereby the turntable 206 and the guide cone 212 are turned. a

To operate the apparatus shown in Figs. 1 to 12 inclusive the cover 115 is raised to locate the endless motionpicture film G upon the turntable 95. The film is spirall wound around the guide cone 86 after whic the cover 115 islowered in place. During the operation of the machine'the film'G is led from its core,through the guide loops 120 and 120', bears against the guide roller 194 and from thence s engaged. by the film sprocket wheel 163. The presser roller'K maintains the film in operative contact with the sprocket wheel 163. The film G next bears against the adjustable guide post 178 and then has formed therein a. loop G. From the said loop G the film is guided between the film guide plate 180 and the springs 184. The latter maintain the film in proper position as it travels in contact with the guide plate 180.

The film G next leads to the film' sprocket wheel 151 to which it is maintained in operative contact by the presser roller J. A loop G is then formed in the film G after wh ch it passes over the film sprocket wheel 156 to which latter it is maintained in operative contact by the presser roller H. The film G is then led around the guide roller 195 and is spirally wound around the guide cone 86 from which it was first led.

To move the film G the electric motor is started which rotates the armature shaft 61'and thereby the spur gear is turned. The spur gear 70 turns the idler gear 73, which latter turns the spur gear in the same direction as the spur gear 7 0 is turned. The shaft 74 turns with the spur gear 75 and thereby the worm 76 turns the worm worm wheel 84 and thereby the guide cone 86 is turned and the motion picture film is discharged from its core and led through the guide loop having the arms 120 and 120" and from thence as already described.

The springs 123 and 124 maintain the windings of the film G in eccentric relation to the guide cone 865 with a crescent shaped clearance space M between the core of the film and the said guide cone. The inclination of the wall of the guide cone and the clearance space M enables the film to make a turn or twist of ninety degrees in the body thereof, to be enabledto rise to a higher level, as it isdischarged at its core and enters the guide 100 To direct t e film to a higher level with the body thereof in a vertical plane would allow it to be easily broken.

With the rotations of the spur gear 7 0 the worm 71 turns the worm wheel 105. The sleeve 97 turns with the worm wheel 105 and thereby the turntable 95 is turned to spirally wind the film around the guide cone 86.. As the film G passes the opening 183 in the cover 182 and the opening 181 in the film guide plate 180 'the normally vertical axes of the pictures on the film being in a horizontal plane the rays of light from the lamp 35 pass therethrough and impinge against the prism 188. By this means the pictures on the film are projected on the vertical face 188 of said prism 188. From the vertical face 188 of the prism the pictures are reflected to the horizontal face 188" thereof. From the horizontal face 188 of the prism 188 the pictures are reflected to the mirror 21 and from the latter they are reflected on the projecting plate or screen 22 to be observed through thehood 23 in their upright position.

The worm wheel 105 is larger in diameter than the worm wheel 84 whereby the guide cone 86 rotates at a greater speed than the turntable 95. By this means the outer windings of the film G travel slower than the windings at its core, and the tensions of the film at its outer and inner windings are equalized, permitting the film to evenly wind and unwind during the operations.

In the modification shown in Figs. 13,

let and 15, the rotations of'the armature shaft 61, rotates the worm 201 and the latter turns the worm wheel 215. The spindle 82, guide cone 212 and the turntable 206 turn with the worm wheel 215. In this modification the guide cone 212 at its lower face 220 is in frictional contact with the turntable which permits the guide cone to run ahead of the turntable if excessive tension is imparted to the film.
